By the third year of teaching I’d begun to expect Christmas break more for the school holiday and less for the excitement of the children. I was teaching fourth grade and my students had made me 36 . I just had to get through one of the hardest days of the school year. The morning bell rang. I walked 37 through the cold into the overly heated school building. Twenty-two smiling faces 38 me at the school bus stop. I forced myself to 39 their smiles. Back into the classroom, they 40 , comparing plans for the 41 . I had to remove one student from each arm 42 I could take a seat at my desk for my morning duties. Before I could find my roll book（点名册） my desk was covered with 43 and gifts followed by a 44 of “Merry Christmas” wishes. “Oh, thank you,” I must have 45 a million times. Each gift was truly special to me, except my 46 mood（情绪）. It was kind of them to 47 me. After a while, I heard a small nervous 48 say my name. I looked up to see Brandon standing 49 by my desk, holding a small, round gift. “This is for you.” “Thank you, Sweetheart.” I laid it on my desk with the others. “Um, could you 50 it now?” I gently tore at the paper and tape. “ 51 ,” he said, “it’s breakable.” Slowly I opened a small, green Christmas tree ornament（装饰物）, complete with a hook already 52 . It dawned on me what he had done. Then a nearby student said that he just pulled that off his own tree. I tried to keep my 53 back. Later that day, I sat 54 the ornament in my hands. Was I really so important to this child that he had searched for something to give me? Now every year as I 55 pull a green Christmas ball from my ornament box, I remember the deep influence my students have on me.
